If you think fleas are only a summer problem, think again. Across Australia, flea season can vary depending on where you live. Some states deal with it all year long. Knowing when fleas are most active in your area means you can act early, protect your pets, and avoid the stress of an infestation.
Here’s your state-by-state guide to flea season in Australia, including what to watch for, when to step up prevention, and how it all ties in with tick season in Australia.
Flea Season QLD
Queensland’s warm, humid climate makes it a hotspot for fleas almost all year round.
- Peak season: September to April
-
High-risk areas: Brisbane, Gold Coast, Far North QLD
Because the climate rarely dips into cold territory, flea season in QLD overlaps heavily with tick season in Australia. Using flea prevention year-round is essential here.
Flea Season NSW
New South Wales experiences more seasonal variation, but fleas are still a big concern during the warmer months.
- Peak season: October to March
-
Watch zones: Coastal NSW, Sydney suburbs, Northern Rivers
Flea season in NSW tends to ramp up in spring and peak through summer, especially in regions with bushland or damp environments.
Flea Season Victoria
Victoria’s cooler climate gives some relief, but not a pass.
- Peak season: November to February
-
Problem areas: Melbourne suburbs, Gippsland, and coastal towns
Flea season in Victoria may be shorter, but fleas can still thrive indoors and in heated homes. Be extra mindful if your pets sleep on your bed or couches.
Flea Season TAS (Tasmania)
Tasmania sees fewer fleas overall, but they’re still active during the warmer months.
- Peak season: December to March
-
Areas to monitor: Eastern coastlines and bushwalk regions
While flea season in TAS is mild, don't skip prevention, especially if you travel with your pets to higher-risk states.
Flea Season WA
Western Australia’s climate varies greatly from north to south, and so does flea activity.
- Peak season: October to April (in warmer areas)
-
Higher-risk regions: Perth, Broome, and rural northern WA
Flea season in WA can be year-round in hotter areas, but tends to spike in late spring and summer.
Flea Season NT (Northern Australia)
In tropical regions like the NT, fleas are a year-round issue due to consistent heat and humidity.
- Peak season: All year, with spikes in the wet season (November to April)
-
Hot zones: Darwin and Top End regions
If you're dealing with flea season in the NT, prevention is a standard. Combine your flea treatment with tick prevention for full coverage.
How to Stay Ahead of Flea Season
No matter where you are in Australia, fleas can become a major issue if left unchecked. Here’s how to stay on top:
- Use monthly flea protection tailored to your pet’s size and needs
- Wash bedding and vacuum soft furnishings regularly
- Check your pets often, especially if they scratch more than usual
- Know the fleas in bed signs so you can act early
- Keep your home and yard clean and pet-friendly
- Use combined flea and tick treatments if you live in a high-risk area (see our guide on tick season in Australia)
